We examine the effect of news media consolidation on local business news dissemination and its consequences for local investors and capital markets. We use acquisitions of television stations by Sinclair Inc. as plausibly exogenous shocks to local news coverage since Sinclair is alleged to reduce local news budgets and homogenize news coverage. Using large-scale television transcripts data, we find that coverage of local firms drops substantially following Sinclair acquisitions. Further, we document that investor attention, trading, portfolio holdings, and stock return synchronicity all become less locally concentrated for firms in treated geographic areas, and that the informational advantage of local analysts decreases and bid-ask spreads increase. The results are pronounced for small firms, for stations with higher ex-ante viewership, and for stations with greater decreases in local coverage. In combination, these results provide insight into the consequences of media consolidation for local business coverage, investors, and capital markets.
